Suppose you are using a shared hosting environment and want to control the maximum size of file uploads for your PHP applications (like WordPress, Laravel, etc.). In that case, you can often do this by modifying the php.ini file provided by your host that allows custom PHP settings.<\/p>\n

This guide shows how to increase or limit the upload size using php.ini in shared hosting.<\/p>\n

Follow the steps to change upload limits using php.ini in Shared Hosting:<\/strong><\/p>\n

    \n
  1. Check if Your Hosting Supports Custom php.ini<\/strong>:
    \nSome shared hosting providers allow a per-directory php.ini. Check your control panel (like cPanel) or ask support whether you can use custom php.ini files.<\/li>\n
  2. Create or Edit the php.ini File:\n
      \n
    1. In the root directory of your website (e.g., public_html), create or edit a file named:\n
      ini<\/pre>\n<\/li>\n
    2. Add or update the following lines:\n
      upload_max_filesize = 10M\r\npost_max_size = 12M\r\nmax_execution_time = 30<\/pre>\n
      Here\u2019s what these settings do:<\/strong><\/p>\n
        \n
      1. upload_max_filesize<\/strong> defines the maximum size allowed for a single file upload.<\/li>\n
      2. post_max_size<\/strong> sets the maximum size of the entire POST request, which should be slightly higher than upload_max_filesize.<\/li>\n
      3. max_execution_time<\/strong> determines how long a PHP script is allowed to run before timing out (useful when uploading large files).
        \nYou can increase the values (e.g., 20M, 50M) based on your requirements.<\/li>\n<\/ol>\n<\/li>\n<\/ol>\n<\/li>\n
      4. (Optional) Modify .htaccess if php.ini doesn\u2019t work:
        \nIf php.ini changes aren\u2019t applied, try adding these lines to your .htaccess file (in the same directory):<\/p>\n
        php_value upload_max_filesize 10M\r\nphp_value post_max_size 12M\r\nphp_value max_execution_time 30<\/pre>\n
        Note: Not all shared hosts allow .htaccess PHP directives. If your site throws a 500 error after this, remove these lines.<\/li>\n
      5. Check if the Changes Are Applied by Creating a PHP Info File:\n
        <?php phpinfo(); ?><\/pre>\n
        Upload the file to your hosting account, open it in your browser, and check the values for upload_max_filesize and post_max_size.<\/li>\n<\/ol>\n
        Important Notes:<\/strong><\/p>\n
